Gas Line Repair in Wilmington, MA
Wilmington runs on both: 32% mains gas, 9% tank propane, 40% on gas of some kind. The two arrangements answer the ownership question completely differently.
Read this first
Mains gas heats 32% of homes in Wilmington and tank gas another 9%. The difference matters more than the fault does at first, because only one of the two has a meter outlet where the utility's responsibility stops.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Wilmington is supplied
In a town with both, the useful page is the one about the arrangement you actually have. The meter is the tell: if there is one, there is a service line behind it and a boundary at its outlet.
| Households in Wilmington | Share |
|---|---|
| Utility (mains) gas | 32% |
| Bottled or tank propane | 9% |
| Electricity | 5% |
| Fuel oil and kerosene | 53% |
| Wood and everything else | 2% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 7,871 occupied housing units. This is the heating-fuel table. It does not enumerate service lines, and no table does at this geography; what it gives is the best available indication of which arrangement a property is on. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Massachusetts as a whole, 56% of households are on mains gas and 4% on tank propane. Wilmington sits 24 points below the state on mains and 5 points above it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
8-1-1 is free and nationwide, and PHMSA gives callers a 99 percent chance of avoiding an incident, injury or worse. Ask them what they will and will not mark: privately owned buried lines on your own side of the meter frequently are not covered.

What to ask whoever quotes it
Ask which side of the meter the work is on before anything else. On the utility side it may not be a contractor job at all, and a quote that has not established that has not established whose problem it is.

Checking a plumber in Massachusetts
Massachusetts licenses are issued by the Massachusetts Board of State Examiners of Plumbers and Gas Fitters, which publishes a public search you can use before work begins.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Other Wilmington requests are covered by the same line.
